本研究的目的是评估99 mTc-高锝酸盐扫描在胃束带渗漏诊断中的价值。
方法
3例病态肥胖患者接受腹腔镜可调节硅胶胃束带术（ASGB），但体重没有明显减轻。为了排除带泄漏的原因，进行了四次腹腔造影程序，包括在将3 mL（111 MBq）高锝酸盐溶液注射到ASGB储液器后30 min和3 h对上腹部进行成像。在1例患者中，在将水溶性造影剂注入ASGB储液囊后，首先通过放射学评估ASGB器械的完整性。
结果
在两个正常工作的ASGB器械中，在早期和晚期图像上均观察到器械内的放射性示踪剂。在两名经手术证实储液囊或连接管存在小泄漏的患者中，后期图像显示储液囊和连接管中几乎没有示踪剂。然而，由于高锝酸盐在皮下或腹膜血管中的再吸收以及随后的胃吸收，在胃中观察到强烈的示踪剂积累。在后一位患者中，ASGB器械的影像学评估未发现异常。
结论
99 mTc-高锝酸盐扫描是诊断ASGB装置中小泄漏的有价值的技术。
UNLABELLED
The purpose of this study was to assess the value of 99mTc-pertechnetate scanning in the diagnosis of gastric banding leaks.
METHODS
Three patients with morbid obesity received laparoscopic adjustable silicone gastric banding (ASGB), but no significant weight reduction was obtained. To exclude band leakage as the cause, four scintigraphic procedures were performed, consisting of imaging the upper abdomen 30 min and 3 h after injection of 3 mL (111 MBq) pertechnetate solution into the ASGB reservoir. In one patient, the integrity of the ASGB device was first assessed radiologically after injection of a water-soluble contrast agent into the ASGB reservoir.
RESULTS
In two normally functioning ASGB devices, radiotracer was observed within the device on both early and late images. In two patients with a surgically proven small leak in the reservoir or the connecting tube, late images showed little tracer in the reservoir and the connecting tube. However, intense tracer accumulation was observed in the stomach as a result of resorption of pertechnetate in the subcutaneous or peritoneal blood vessels and subsequent gastric uptake. In one of the latter patients, radiographic assessment of the ASGB device revealed no abnormalities.
CONCLUSION
99mTc-pertechnetate scanning is a valuable technique to diagnose small leaks in an ASGB device.
